offers a Grounding "Attachment" Point for the Radio.


My car radio is isolated from ground by four large rubber doughnuts and
still manages to outperform most of the in-house am radios, using an
obscenely small antenna on top of it all.

Your advice would imply that dragging ten or twenty feet of logging
chain from the chassis would reduce signal noise, at least on wet days.

Is that really a logical conclusion? I'm having problems with your
assumptions.
